BACKGROUND: Plastic as a durable, inexpensive, easy to manufacture organic synthetic polymer materials are widely used. At the same time, plastic resistance to high temperatures, acid and alkali resistance, corrosion-resistant properties make it difficult to degrade in nature, and ultimately forming a huge number of microplastic pollution threatening human health. OBJECTIVE: To investigate the effects of microplastic exposure on growth and development and hepatic lipid metabolism in mice. METHODS: Twenty C57BL/6J male mice were adaptively fed for one week, and then randomly divided into normal and microplastic groups (n=10 per group). Mice in the normal group were given a normal diet and water, for 4 weeks. Mice in the microplastic group were given a normal diet and free drinking of microplastic (polystyrene) water with a concentration of 1 000 μg/L, for 4 weeks. At 2 and 4 weeks of drinking, body mass and grip strength, blood lipids and liver and kidney function, ultrasonic morphology and pathological morphology of liver and lipid deposition were detected. RESULTS AND CONCLUSION: (1) With the extension of time, the body mass of mice in the two groups gradually increased, and the body mass of mice in the microplastic group was greater than that in the normal group after 2, 4 weeks of drinking water (P < 0.05). With the extension of time, the grip strength of mice in the normal group gradually increased, and the grip strength of mice in the microplastic group first decreased and then increased, and the grip strength of mice in the microplastic group was lower than that in the normal group after drinking water for 4 weeks (P < 0.05). (2) Liver ultrasound examination showed that compared with the normal group, the ultrasonic echo signal of the liver in the microplastic group was enhanced after 2 and 4 weeks of drinking water. (3) Hematoxylin-eosin staining showed that the morphology of liver cells in the microplastic group did not change significantly after 2 and 4 weeks of drinking water, but inflammatory cell infiltration could be seen. Oil red O staining showed that obvious lipid deposition was observed in the liver of microplastic group after 2 and 4 weeks of drinking water. (4) Compared with the normal group, the levels of serum high density lipoprotein cholesterol, triacylglycerol, and aspartate aminotransferase in the microplastic group were decreased after 2 weeks of drinking water (P < 0.05), and the serum triacylglycerol concentration was decreased after 4 weeks of drinking water (P < 0.05). (5) These findings confirm that microplastics may cause weight gain, loss of physical strength, and abnormal hepatic lipid metabolism in mice. [ABSTRACT FROM AUTHOR]

Using polyvinylidene fluoride (PVDF) organic membrane as substrate and tannic acid (TA) as binder, spinel NiAl2O4, inorganic nanoparticles were uniformly modified on the surface of PVDF membrane to prepare super-hydrophilic/underwater super-oleophobic NiAl2O4/TA/PVDF composite membrane. The structure, morphology and surface wettability of the NiAl2O4/TA/PVDF composite membrane were systematically studied, and the performance of the composite membrane in the separation of typical oil-water emulsions was evaluated. The experimental results showed that the NiAl2O4/ TA/PVDF composite membrane exhibited excellent separation efficiency (separation efficiency is above 99%) and higher permeation flux (682-1 302 L. m-2. h-1) for stable oil-water emulsions. In addition, due to the rough structure and special wettability of the membrane surface, NiAl2O4/TA/ PVDF composite membrane has good oil pollution resistance. After eight cycles of separating oil-in- water emulsion, it still has high separation efficiency and permeation flux, showing good mechanical properties and reproducibility. This research provides a new idea for the construction of spinel-based oil-water separation membranes and their applications in oil-water separation. [ABSTRACT FROM AUTHOR]

The development of deep-sea exploration technology is of great significance to the study of global environmental changes, the exploration of life origin, the search for seabed resources, and the assessment of marine pollution, and has become an important direction of today's scientific and technological development. Traditional analytical techniques require seawater to be sampled, stored, and then transferred to a laboratory for analyzing, which not only consume time, but also result in biased results. The in situ detection technology can realize long-term, real-time continuous detection, which can solve the problem of sample storage and improve the detection accuracy. Mass spectrometry has abilities to qualitatively and quantitatively analyze low-concentration substances, which is suitable for in situ analysis. But compared with ground-based applications, the enormous pressure of the deep ocean brings challenges to the analysis of mass spectrometry in the ocean. Mass spectrometry instruments need to work in a high vacuum environment, which require that the sampling system must be able to withstand the pressure difference between the high-pressure liquid and the high vacuum inside the instrument. In order to realize the application of mass spectrometry detection technology in deep-sea exploration, a membrane sampling device capable of withstanding ultra-high water pressure was developed based on the injection technology of volatile organic compounds and dissolved gases in high-pressure liquid environment. The device processes porous sintered rods, vacuum plugs and sampling stainless steel tubes into an integrated sampling structure through a welding process, then coated a hydrophobic membrane, and used ultra-high vacuum sealant to fix and seal the membrane and sampling structure. Therefore, it is ensured that it has sufficient mechanical structural strength, so that the sample injection device can work directly under ultra-high pressure for a long time. A high pressure test environment was constructed by using a high performance liquid chromatography pump and a back pressure regulator, and the pressure resistance test of the ultra-high pressure membrane sampling device was carried out. The test results showed that the device had worked for more than half a month under water pressure of 40 MPa. The sampling device was applied to the online mass spectrometry system, and the sampling efficiency of benzene series and other substances under different pressures, temperatures and flow rates was tested.

In order to study the effects of different Western Pacific subtropical high on Meiyu precipitation, based on the monitoring indicators of the Western Pacific subtropical high (WPSH) from 1951 to 2016, the cluster analysis of the WPSH in June and July was carried out by using self-organizing map (SOM), and nine SOM types were obtained. Using 1 km monthly precipitation dataset for China (1901—2017) and the information table of rainy seasons in China, according to the Meiyu area defined by the Meiyu monitoring indices, the characteristics of Meiyu precipitation under different WPSH types were analyzed. The results show that the location of the WPSH jumps frequently in 66 years, resulting in many changes in the characteristics of Meiyu precipitation. Latitudinally, when the WPSH is to the east, the precipitation intensity in Meiyu area is low, otherwise, the intensity is high. Longitudinally, on the premise that the WPSH is mainly located on the land of China, when the ridge line index is higher than 25 °N, most of the Meiyu area is controlled by the WPSH, the overall precipitation is less, and there is a trend of less in the south and more in the north. When the ridge line index is low, the WPSH controls the southern edge of Meiyu area or more south area, and the water vapor transport leads to more precipitation as a whole. The corresponding relationship between different types of subtropical high and Meiyu precipitation characteristics is obtained, which also shows that SOM method can better objectively classify meteorological elements such as subtropical high, and then carry out the correlation study of climate phenomena.
